Digital Color Cameras use CCD arrays to capture images. These arrays have a certain definite pattern to them. The Bayer Color Array is one of the most commonly used. Colors are subsampled and mosaicked, which requires estimation of missing colors at the points where a sample is not obtained. This project looks into the various interpolation methods available. A comparative performance study shall be made of the bilinear, gradient-based methods; which shall encompass metric differences and also differences that arise due to the algorithm involved (e.g. bandlimiting). The metrics for comparison include mean squared error and \delta E error in the L*a*b* color space (perceptually uniform).
